SKL-A-102 hardware-software independent complex for geophysical surveying of the production wells
The Complex serves for geophysical surveying of the open boreholes of the horizontal and directional wells of 120-245 mm diameter being drilled for oil and gas, both while tripping the complex in and while tripping it out. The complex runs to bottomhole on a drilling tool.
Advantages of the Complex:
geophysical surveying is performed during one trip
reduction of downtime
low sticking hazard
estimation of relative dielectric permeability, which allows to separate oil-saturated reservoirs from the reservoirs washed with fresh and mixed waters
